- Develop scalable backend services and APIs using **Python**
- Integrate LLMs with external data sources, APIs, tools, and enterprise systems
- Develop solutions involving prompt engineering, retrieval-augmented generation (RAG), tool calling, and AI agents
- Deploy and maintain AI applications within a major cloud environment
- Collaborate with engineers, product stakeholders, and clients to translate business requirements into technical solutions
- Evaluate emerging AI/LLM technologies and identify opportunities to improve existing solutions
- Write clean, maintainable, well-tested code suitable for production environments
- Troubleshoot, optimize, and improve the performance, reliability, and scalability of AI applications

### What We're Looking For

- Experience working with at least one major cloud platform:
  - AWS
  - Google Cloud Platform (GCP)
  - Microsoft Azure
- Strong understanding of software engineering fundamentals, APIs, and application development
- Experience building or integrating **LLM-powered applications**
- Ability to work independently in a remote environment while collaborating effectively with a distributed team

### Nice to Have

- Experience with **LangGraph**
- Experience building **AI agents or agentic workflows**
- Experience with **RAG**, vector databases, embeddings, and semantic search
- Familiarity with OpenAI, Anthropic, Gemini, or other foundation models
- Experience with Docker and/or Kubernetes
- Experience with CI/CD and production cloud deployments
- TypeScript experience
- Experience working in a consulting or client-facing environment

### Education

A Bachelor's degree is not required if the candidate has strong relevant experience. **Master's or PhD graduates with relevant hands-on experience in AI, machine learning, computer science, or a related field are encouraged to apply.**

This role is **not intended for candidates coming directly from an undergraduate program without professional or substantial project experience.**
